Oh crap. Its worse even than QETWidget::translateKeyEventInternal(). AFAICS, 
languages such as Bengali are completely missing...and more research on the 
web turns up links like this:

http://cvsweb.xfree86.org/cvsweb/xc/lib/X11/imKStoUCS.c

with what looks like more of the story. Unless someone has a better idea, I'll 
have to see if I can find a synthesis for all this. 

For the record then, I'm going to try[1] to build a translation module from 
X11 keysyms to Unicode. I'll stick what I come up with in viki for now, and 
we can consider if anyone needs this moving to (say) kdecore/kkey* in 4.0.

Thanks, Shaheed

[1] To my increasing chagrin, even keysymdef.h does not seem to have Indic 
keysym symbols. Any pointers appreciated...
